| 摘 要： | 本文详细地讨论了用基线法标定重力仪小周期(周期小于1mGal=10~(-5)ms~(-2)误差的有关问题,同时指出:按国内现有条件和现行的观测程式难以精确确定小周期误差,借以改正观测值的意义不大,甚至有时还会损害原有的观测精度。

On the Calibration of the Small Periodic Terms for Gravimeter |
| |
| Abstract: | Problems about the possibility of calibrating the small periodic error (order lessthan 10~(-5)ms~(-2))are discussed in this paper. The idea is that it is impossible to calibrate the small periodic terms accurately by using the gravimetrie baselines now available in China. Even worse, it may damage the observation' s accuracy when they are introduced in adjustment. |
